The lawmakers drew a line that favours the rich. When you have companies making millions paying more in taxes than the common folk who barely scrape by. The lawmakers do it because of the rich lobbying them. Something the most people don't have the money for.
For sure everyone does their best to minimise the taxes they pay, but when you are the richest person in the world with some $200 billion, maybe you should be doing silly schemes like charity for tax avoidance.
Heck I tend to minimise my taxes, but often I don't even have such opportunity. The best I can do right now is contribute to my pensions. I'm on a current tax rate of around 50%. Outside that, there's not a lot I can do to minimise the tax I pay. Compare that the rich, who through their lobbying, and their schemes have paid an effective tax rate of around 3% over 5 years.
My statement is ridiculous to the rich, not so much to the rest of the population.
